White tongue/Mono

About 1 month ago, I had a terrible sore throat and had ulcers forming.  I was put on antibiotics and within a day, my tongue was white and the ulcers had worsened.  I was tested for mono and it came back positive.  Since, my throat has gotten better, but my tongue is still white.  I went back to my doctor, who put me on a medication for thrush, however the tongue hasn't gotten any better.  The white tongue looks almost fuzzy on top and cannot be scraped off.  Any scraping or brushing results in irritated bumps on the tongue and bleeding.  Another mono test revealed a second positive mono test, however do I need to be worried about the tongue? Thanks.

Hairy tongue is generally innocuous.
